Does jBPM has any document attachment function?

[aldray]

Hi, how can the document attachment to a process instance be done?

e.g. i attach a letter (abc.doc) to to sent out to a customer in a draft task. The letter is then reviewed by another user at the review task.

The letter will get updated and versioned.

How can this be done in jBPM? Is there any in-built modules or is there any open-source to do this?

Regards,

It sound like a task for Alfresco (www.alfresco.org) or maybe if you want to do your code you should take a look at:
